Abstract (en)

[origin: WO2019229680A1] A porous membrane includes a triblock copolymer of the formula ABC. B is a hydrogenated vinyl aromatic block present in a range from 30 to 90 weight percent, based on the total weight of the copolymer and has a Tg of ≥110oC. C is a rubbery block present in a range from 10 to 70 weight percent, based on the total weight of the copolymer and has a Tg ≤ 25oC. A is substantially incompatible with both the B and C blocks and is derived from ring-opening polymerization. B + C is present in a range from 70 to 95 weight percent, based on the total weight of the copolymer.
